Description

Technical Field

[0001] This utility model relates to the field of welding technology for the chassis frame of a weeder, specifically a welding positioning platform for the chassis frame of a weeder. Background Technology

[0002] A lawnmower, also known as a lawn mower or lawn trimmer, is used for weeding or mowing. A lawnmower typically consists of a walking mechanism, a blade disc, a power unit, and other main components. The entire structure of the lawnmower is fixed to its chassis, and the chassis frame is generally assembled and fixed by welding.

[0003] According to a public notice (Announcement No.: CN219966893U) of a weeder chassis frame welding platform, the above application sets up a welding platform for placing the unwelded chassis frame, and sets up several positioning plates on the welding platform to assemble and fix the frame. The positioning plates are provided with two positioning pins that move with the clamping plates to clamp and fix the frame. The position control component can control the clamping structure to adapt to different clamping positions.

[0004] However, in actual use, when the above-mentioned equipment limits the position of a small weeder chassis frame, the distance between the positioning holes on the upper surface of the platform is consistent, which makes it impossible for the clamping plate to make fine adjustments to the distance between itself and the weeder chassis frame. This makes it impossible to effectively limit the position of the weeder chassis frame. In view of this, we propose a welding positioning platform for the weeder chassis frame. Utility Model Content

[0005] The purpose of this utility model is to provide a welding and positioning platform for the chassis frame of a weed cutter, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a welding and positioning platform for a weed cutter chassis frame, comprising a mounting plate, wherein a limiting component is provided on the upper surface of the mounting plate, and the limiting component includes:

[0007] A limiting hole is provided on the upper surface of the mounting plate. A lead screw is sleeved inside the limiting hole, and a large nut is threaded onto the outer surface of the lead screw. An installation rod is fixedly connected to the end of the lead screw.

[0008] The mounting component is fixedly connected to the end of the mounting rod, and a motor is fixedly connected to the side of the mounting component. A large threaded rod is fixedly connected to the output end of the motor, and a pressing component is threadedly connected to the outer surface of the large threaded rod.

[0009] The placement groove is located on the side of the pressing member. A rotating member is rotatably connected to the bottom of the inner wall of the placement groove. A top plate is threadedly connected to the outer surface of the rotating member. A limit block is hinged to the top of the pressing member. Bolts are provided on the side of the pressing member away from the placement groove.

[0010] Preferably, the rotating component is composed of a threaded rod fixedly connected to the side of the rotating block, and the size of the rotating component is adapted to the size of the placement groove, which allows the rotating component to rotate inside the placement groove.

[0011] Preferably, the position of the bolt corresponds to the position of the limiting block, and the end of the bolt is arranged to penetrate the pressing member into the limiting block, which allows the bolt to limit the pressing member.

[0012] Preferably, the size of the pressing member is adapted to the size of the mounting member, and the upper surface of the top plate is provided with a semi-circular protrusion, which increases the friction between the upper surface of the top plate and the chassis frame of the weeder.

[0013] Preferably, an auxiliary component is provided on the side of the top plate. The auxiliary component includes a connecting rod, which is rotatably connected to the side of the top plate. A sliding groove is provided on the side of the connecting rod. A small threaded rod is fixedly connected to the side of the mounting component, and a small nut is threaded onto the outer surface of the small threaded rod.

[0014] Preferably, the size of the small threaded rod is adapted to the size of the slide groove, and the small threaded rod is disposed inside the slide groove.

[0015] Preferably, the side of the small nut is in contact with the side of the connecting rod.

[0016] Compared with the prior art, this utility model provides a welding and positioning platform for the chassis frame of a weed cutter, which has the following advantages:

[0017] 1. The positioning platform for the chassis frame of this weeder is designed to better limit the positioning of the chassis frame. A lead screw is inserted into the limiting hole on the upper surface of the mounting plate, and a large nut is used to limit the lead screw. The motor is then started, causing the large threaded rod to rotate, which in turn moves the pressing component closer to the chassis frame, bringing the bottom of the chassis frame into contact with the upper surface of the top plate. Simultaneously, a movable limiting block is used, positioned perpendicular to the pressing component. A bolt is inserted through the pressing component into the limiting block, and the rotating component is rotated, causing the top plate to move upwards, thus better limiting the positioning of the chassis frame.

[0018] 2. The positioning platform for the chassis frame of the weeder is designed to ensure the chassis frame is more stably positioned. During the positioning process, the top plate moves, causing the small threaded rod to move within the slide groove. After the top plate, in conjunction with the positioning device, positions the chassis frame, the small nut is rotated to contact the connecting rod, thus positioning the connecting rod and providing support to the top plate. This ensures the chassis frame is more stably positioned. Attached Figure Description

[0024] like Figures 1-4 As shown, this utility model provides a technical solution: a welding and positioning platform for the chassis frame of a weed cutter, including a mounting plate 1. A limiting component 2 is provided on the upper surface of the mounting plate 1. The limiting component 2 includes a limiting hole 201, a lead screw 202, a large nut 203, a mounting rod 204, a mounting piece 205, a motor 206, a large threaded rod 207, a pressing piece 208, a placement groove 209, a rotating piece 210, a top plate 211, a limiting block 213, and a bolt 212.

[0025] In this embodiment of the utility model, a limiting hole 201 is formed on the upper surface of the mounting plate 1. A lead screw 202 is sleeved inside the limiting hole 201. A large nut 203 is threaded onto the outer surface of the lead screw 202. An installation rod 204 is fixedly connected to the end of the lead screw 202. An installation component 205 is fixedly connected to the end of the installation rod 204. A motor 206 is fixedly connected to the side of the installation component 205. A large threaded rod 207 is fixedly connected to the output end of the motor 206. A pressing component 208 is threaded onto the outer surface of the large threaded rod 207. The size of the pressing component 208 is adapted to the size of the installation component 205. A placement groove 209 is formed on the side of the pressing component 208. A rotating component 210 is rotatably connected to the bottom of the inner wall of the placement groove 209. The rotating component 210 is composed of... The rotating block is fixedly connected to a threaded rod on its side. The size of the rotating part 210 is adapted to the size of the placement groove 209, which allows the rotating part 210 to rotate inside the placement groove 209. The outer surface of the rotating part 210 is threadedly connected to a top plate 211. The upper surface of the top plate 211 is provided with a semi-circular protrusion, which increases the friction between the upper surface of the top plate 211 and the chassis frame of the weeder. The top of the pressing part 208 is hinged to a limiting block 213. The side of the pressing part 208 away from the placement groove 209 is provided with a bolt 212. The position of the bolt 212 corresponds to the position of the limiting block 213. The end of the bolt 212 is provided through the pressing part 208 to the inside of the limiting block 213, which allows the bolt 212 to limit the pressing part 208.

[0026] Meanwhile, an auxiliary component 3 is provided on the side of the top plate 211. The auxiliary component 3 includes a connecting rod 301, which is rotatably connected to the side of the top plate 211. A groove 302 is provided on the side of the connecting rod 301. A small threaded rod 303 is fixedly connected to the side of the mounting component 205. The size of the small threaded rod 303 is adapted to the size of the groove 302. The small threaded rod 303 is located inside the groove 302. A small nut 304 is threadedly connected to the outer surface of the small threaded rod 303. The side of the small nut 304 is connected to the connecting rod 301. The sides are in contact, so that when the top plate 211 moves during the process of limiting the chassis frame of the weeder, the small threaded rod 303 will move inside the slide groove 302. After the top plate 211 and the limiting block 213 limit the chassis frame of the weeder, the small nut 304 is rotated so that the side of the small nut 304 contacts the connecting rod 301, thus limiting the connecting rod 301. This allows the connecting rod 301 to support the top plate 211, so that the chassis frame of the weeder can be more stably limited.

[0027] In this utility model, during use, the lead screw 202 is inserted into the limiting hole 201 on the upper surface of the mounting plate 1, and the lead screw 202 is limited by the large nut 203. Then, the motor 206 is started to rotate the large threaded rod 207, which causes the pressing member 208 to move closer to the weeder chassis frame, so that the bottom of the weeder chassis frame contacts the upper surface of the top plate 211. At the same time, the movable limiting block 213 is set perpendicular to the pressing member 208. The end of the bolt 212 passes through the pressing member 208 and enters the limiting block 213. The rotating member 210 is rotated to move the top plate 211 upward, which, together with the limiting block 213, better limits the weeder chassis frame.

[0028] Furthermore, during the process of limiting the chassis frame of the weeder, when the top plate 211 moves, it will cause the small threaded rod 303 to move inside the slide groove 302. After the top plate 211 and the limiting block 213 limit the chassis frame of the weeder, the small nut 304 is rotated so that the side of the small nut 304 contacts the connecting rod 301, thereby limiting the connecting rod 301. This allows the connecting rod 301 to support the top plate 211, making the chassis frame of the weeder more stably limited.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
